To all nil mm it may concern.-

Be it known that I, HEMAN OSBORNE, acitizen of the United States of America, and a resident of Springfield,in the county of Ham pden and State of Massachusetts, have invented certain new and useful Improvements in Shutter-Vorkers, of which the following is a full, clear, and exact description.

This invention relates to improvements in shutter-workers of the kind which are adapted to be operated from the interior of the building, and more particularly appertains to that description of shutter-worker in which there is comprised a worm which is positively operated as desired through operating means accessible within the room, and which worm in turn operates a worm-wheel or gear-wheel, between which and the hinged shutter is a medium of connectionwhereby the rotary motion as positively imparted to. the worm wheel causes a swinging motion in the desired direction for opening or closing the shutter or for placing and holding the shutter in any position to which it may be swung between its extremes of opened and closed positions, and in this class of shutter-workers, comprising the Worm-wheel and worm, the shutter necessarily remains locked or set wherever it may wilfully have been placed 0 by the manipulation of the mechanism-from the interior, the necessity of catches or shutter-fasteners being dispensed with.

The object of the present invention is to devise a shutter-worker of the class indicated 5 to embody by a new andingenious arrangement of the component parts a minimum of parts, compactness, simplicity, directness of action, and avoidance of liability to derangement, durability, and the capability of with- 0 standing the results of use for a long time without derangement.

To these endsthe invention consists in certain specific and particular constructions, arrangements, and combinations of parts, all

substantially as hereinafter described, and

set forth in the claims.

Reference is to be had to the accompanying drawings, in Which-- Figure l is a horizontal sectional view through the portion of the window-casing at which the shutter worker is applied, the shutter-worker being shown substantially in plan above the top of the window blind or shutter, a part of which is also shown in plan view. Fig. 2 is a vertical section taken on the line 2 2, Fig. 1. Fig. 3 is a perspective view of the two-part casing within which substantial portions of the operating mechanism are contained, and which casings constitute journalbearings for such operating parts.

Similar characters of reference indicate corresponding parts in all of the views.

In the drawings, A represents a portion of the window-casing havingthe horizontal hole a therethrough.

B represents the blind or shutter,hinged in the ordinary manner at b.

O 0 indicate the two sections or halves of f the case or inclosure for the shutter-working mechanism, the same being advantageously 7o composed of cast-iron and having a straight flat back d, with ear-lugs ff, through which to screw the case securely to the exterior of the window-casing, above the top of the shutter, and said sectional case is also constructed with duplicate matching pairs of ear-lugs ff, through which by the screws 9 the sections of the case are held together in the manner of a close tight shell for the exclusion of moisture and dirt.

The sectional case has at its rear the hollow boss h, which fits into the window-casing hole a. The upper and lower case-sections have the alined bosses 1i i, with journal-sockets j therein, the lower one being extended through to the bottom of the casing. These sockets receive the upper and lower end journals of the worm-wheel 7c. The case-section to the rear of the mounting of the worm or gear wheel is has its opposite side walls thicko ened, as at o, in which thickened portions of each section are the duplicate pairs of matching half-cylindrical sockets m, receiving the end journals n of the shaft D, which has integrally formed by casting therewith the worm 5 or screw E and the double sheave F. The worm meshes into the wheel 70, and in winding engagement with the double sheave are the two cords p p or other equivalent flexible connections, the same extending through the roe hollow boss h and through the hole a and are guided around the double sheave or rollers, and these cords constitute the direct operating means for the shutter-operating mechanism. Tlie lever G, afiixed on the lower end I of the journal of the worm-wheel It, is linked at t to the top of the shutter.

The manner of operating the mechanism will be manifest from the illustrations provided. When one-of the operating-cords is unwound,the other one is wound upon sheave F. The rotation of the sheave in either direction and the corresponding rotation in unison therewith of the worm impart the swinging motion to the lever which is in operating connection with the shutter.

The making of the worm E and the double sheave F as integral parts one with another and with the common shaft which has its mountings or journals provided therefor by mere cavities or sockets in the casing sections, which casing-sections also by right-angularly alined sockets constitute the journals for the worm-engaged Wheel, contribute materially in composing What is deemed by me to be prominent and important specific features of my present invention.

Having thus described my invention, wha I claim, and desire to secure by Letters Patent, is-

1. In a shutter worker, the combination with a casing, a gear rotatably mounted in the casing and having one end of its shaft projecting out of the casing, and means for operating the shutter from the said project iug end of the gear-shaft; of a shaft rotata bly mounted in the casing at right angles to the gear-shaftand parallel with the attaching'side of the casing, a Worm mounted on said last-mentioned shaft and arranged to engage said gear, the attaching side of the casing having an aperture therein located opposite to said worm-shaft, and a winding means projecting through said aperture and arranged to rotate said Worm-shaft.

2. In a shutter-worker, the combination of twopart casing comprising the attachingplate d, and the shell sections C, C, which contain the oppositely-disposed j ournal-sockets i, 71, arranged parallel with the attachingplate, and the oppositelydisposed journalsockets m,m, also arranged parallel with the attaching-plate and at right angles to said journal-sockets; a shaft journaled in the said sockets 41,2', and projecting through one of them out of the casing; means for operating a shutter from said projecting end of the shaft; a gear mounted'on said shaft inside of the casing; a shaft journaled in the said sockets m, m; a worm mounted on the said latter shaft and arranged to engage said gear; a double sheave also mounted on said latter shaft; said attaching-plate having an aper= tureilocated opposite to said sheaves; and a winding means engaging said sheaves and operating through said aperture. 7
